FIRST: If you have drawings for the DCC, please let me know. I have two of them (long in storage in the house, but they ran when I pulled them from their Unitote/Regitel rack a couple of *decades* ago. There is an RDOS - disk images, available at: http://simh.trailing-edge.com/software.html (Top entry in the list) It is about a 2.5MB disk image. I suggest that you might download SimH and that image, configure SimH as a straight Nova (rather than a /3 or /4) and see if it runs that image OK. If so, there you go! Beyond that, I *might* be able to help, but it will depend on what the status of copyright is on what I have, and whether your system can even run what I do have. I am looking into the copyright part of it - that may take a week or two. (This is something I needed to to anyway). In the meantime: Do you have a way to *write* a tape image? I have an AWS format image of an RDOS starter system. Note, however, that the label on the RDOS starter image I have suggests it may only be appropriate for a NOVA 3 or NOVA 4, so it might not run on your system. So, I'd have to take some time to boot it and try and set up a system for a straight Nova. As this would take several hours, I'm not keen on doing that unless you know that one from SimH will not work for you. I also have some OS and compiler DG floppy images, if you have a DG-compatible floppy setup. Several different operating systems there. Same issue: one would have to see how many are compatible with a straight Nova. I have images of the floppies. Diagnostics for DG systems are notoriously difficult to find. I have a few, in listing format. JRJ
